Machine concept with a variable combination of warm-up and caustic zones

“Less is often more“ – the new and improved Lavatec series pays heed to this motto more consistently than ever. The Krones bottle washer surprises with its thrifty water and energy budget. And it proves that „highest-quality hygiene“ can be achieved without a „chemical cudgel“. Lavatec‘s economical treatment of resources is due to its clever construction as a double-end machine with vertical loops and continuous debris removal. This Is explained precisely on the following pages.

Your benefitsOpenClose


  • Highest degree of hygiene
    Construction according to the double-end principle and clean design assures maximum hygiene and safety.
  • Safe operation
    Thanks to its improved mechanics and continuous debris removal, Lavatec operates safely and reliably even in 24-hour operation cycles.
  • Less water and fewer chemical additives
    The continuous debris removal and the multiple-bath design with vertical loops result in enormous savings with respect to the consumption of water and chemicals.
  • Efficient use of energy
    The heating system supplies the best results in heat transmission and reduces energy costs substantially.
  • Gentle transport of the bottles
    Patented carrier systems guide the bottles gently and safely through the machine. The discharge is effected without containers falling and with little noise. Synchronous drives and chain rollers with plastic bushings guarantee the accurate transport of the bottles.
  • Relief of the operating staff
    The inside of the machine is easily accessible and can be cleaned in an optimum manner.

Method of operation

In order to spatially separate contaminated and clean bottles from one another, Lavatec was designed according to the “double-end“ principle:
Bottle Infeed and discharge take place at different locations and thus assure the best possible hygienic conditions. The pre-cleaning system heats the bottles and removes glass fragments and coarse contamination. Subsequently the bottles run through various caustic baths in vertical loops, in order to completely wash away dirt or labels. Before the bottles leave the machine, they are cooled in the post-treatment zones with a small quantity of fresh water and freed of any remaining dirt or caustic residues.


Food-grade cleaning of returnable glass containers.

Layout configurations

The Krones cleaning technology is modularly structured: Single elements for pre-soak tank, the loop guide, and the post-treatment are combined to form an individual bottle washing system. Depending upon the requirements, additional components such as high-pressure pre-jetting, heat recovery and label removal can be included in the presoak tank. For optimum space utilisation, Lavatec is available in different machine heights and widths.


Custom-made: The model variants ideally adjust to the space conditions.

Infeed - DischargeOpenClose


Bottle infeed

Bottle discharge


During the infeed, fingers take over the bottles from the conveyor and transport them safely and exactly to the bottle carriers.


Special discharge fingers transport containers of all shapes and sizes without allowing them to fall and with little noise onto the conveyor.

Drive technologyOpenClose

  • Together with a central frequency inverter, the high-performance synchronous drives allow precise control of the main chain and gentle bottle conveyance.
  • All drive sprockets and endturning devices are divided - this is a significant advantage for later maintenance jobs.

Synchronous drive

Split sprockets facilitate maintenance.



Interior cleaning

Rotating spraying nozzles clean the insides of the bottles from different angles of incidence.



Exterior cleaning

External cleaning is effected from above by patented jetting units.

Clean DesignOpenClose

  • The housing and piping guide systems fulfil the highest hygienic demands and are equipped with central emptying points.
  • The combined coarse and fine filtration renders the use of sieving conveyors and detachable sieves superfluous and ensures high post-caustic purity.
  • The open bottle slide made of one-piece, germ-resistant plastic sections guarantees the best possible hygienic conditions.
  • The easily accessible discharge area enables fast, intensive cleaning.
